Flask-Nicely consists of a simple decorator with which to wrap Flask

functions that return data in order to turn them into pretty, consistent

JSON responses. It also provides several built in HTTP exceptions which can

be raised in a Flask function in order to return the corresponding HTTP

error response.

Docs can be found at http://flask-nicely.readthedocs.org/

Dependencies

------------

Flask-Nicely is tested on both Python 2.7 and Python 3.3. It has only one

dependency: `Flask

`_ itself.

Installation

------------

Flask-Nicely is available on `PyPI

`_. The best way to install is

via pip, as follows:

.. code:: bash

    pip install flask-nicely

Alternatively, you can download the source code directly from GitHub.

Usage

-----

The Flask-Nicely decorator is used as follows:

.. code:: python

    import flask_nicely

    app = Flask(__name__)

    @app.route('/hello/')

    @flask_nicely.nice_json

    def hello(name):

        data = {

            "Name": name,

            "Message": "Hello, {}!".format(name)

        }

        return data

Wrapping our view function in the decorator will cause the view to return the

following 200 response:

.. code:: json

    {

      "data": data,

      "error": null,

      "status": 200,

    }

Flask-Nicely also allows you to throw HTTP exceptions which will result in a

properly formed HTTP error response. Custom exception messages may be entered:

.. code:: python

    from flask import Flask

    import flask_nicely

    from flask_nicely.errors import NotFound

    app = Flask(__name__)

    @app.route('/error/404')

    @flask_nicely.nice_json

    def throw_404():

        raise NotFound("Could not find the grail!")

This will result in the following 404 response:

.. code:: json

    {

      "data": null,

      "error": "Could not find the grail!",

      "status": 404

    }

Exceptions can accept a payload, which is an arbitrary dictionary to be sent

as part of the JSON response. For example:

.. code:: python

   test_payload = {

       'error_detail': "The resource that you requested was not found on the server",

       'documentation': "http://www.flask-nicely.readthedocs.org",

   }

   raise NotFound(payload=test_payload)

Will result in a 404 response containing:

.. code:: json

    {

      "data": null,

      "error": "Not Found",

      "status": 404,

      "error_detail": "The resource that you requested was not found on the server",

      "documentation": "http://www.flask-nicely.readthedocs.org",

    }

An example app can be found in the examples directory, and can be run from

the root directory using:

.. code:: python

    python examples/app.py

Testing

-------

To run the tests for the project using py.test, simply run:

.. code:: bash

    python setup.py test

For multi-version testing, install and run tox:

.. code:: bash

    pip install tox

    tox
